BACKGROUND The total flavonoids from ethanol extract of the aerial part of Ziziphora clinopodioides Lam. (Lamlaceae) (Xintahua) showed protective activities against rat acute myocardial ischemia in rats. This study aims to isolate acacetin, a flavonoid, from the aerial part of Z. clinopodioides, to develop an HPLC method for its detection, and to evaluate its protective effects on neonatal rat ...

In order to investigate the medicinal species from montain of ShirKooh (Up village), in Yazd provience, Iran on three species by scientific names were Heracleum persicum Desf. ex Fisch., C.A.Mey. & Avé-Lall.; Ziziphora clinopodioides Lam. and Nepeta asterotricha Rech.f. were collected on June, July and August 2011. Then all samples essential oils were extracted by hydro-distillation method (cla...

The variability of essential oil characteristics in different phenological stages of Clinopodium pulegium from its natural habitat (Svrljiški Timok gorge, Serbia) and from cultivated plants (Niš, Serbia) was determined. The essential oils were obtained from aerial parts of the plants by hydrodistillation and analyzed by GC-MS. These are the first data on the essential oil characteristics of pla...

(R)-(+)-Pulegone is a monoterpene found in essential oils from plants of the Labiatae family. This compound is a major constituent of Agastache formosanum oil. In this study, the effect of (R)-(+)-pulegone on the central nervous system was evaluated. (R)-(+)-Pulegone caused a significant decrease in ambulation and an increase in pentobarbital-induced sleeping time in mice, indicating a central ...

The composition of essential oil of the leaves of Lavandula stoechas ssp. stoechas, was analyzed by means of capillary GC-MS. The main components of L. stoechas ssp. stoechas oil were pulegone (40.4%), menthol (18.1%), menthone (12.6%). The essential oil of the plant was evaluated for antibacterial and a panel cytotoxic activities.

A comprehensive study on essential oils extracted from different Calamintha nepeta (L.) Savi subsp. glandulosa (Req.) Ball samples from Tarquinia (Italy) is reported. In this study, the 24-h steam distillation procedure for essential oil preparation, in terms of different harvesting and extraction times, was applied. The Gas chromatography-mass spectrometry (GC/MS) analysis showed that C. nepet...
